Quantitative determination of residue amounts of pesticide active ingredients used in grapes by LC-MS/MS and GC-MS/MS devices and evaluation of these pesticides in terms of public health

Abstract

The aim of this study was to quantitatively determine pesticide residues in grapes, one of the most produced and consumed fruits in Turkey and in the world. A total of 226 active ingredients were analyzed in 21 samples collected from Southeastern and Eastern Anatolia regions using QuEChERS (quick, easy, cheap, effective, rugged and safe) extraction method and multiple residue analysis technique and LC-MS/MS and GC-MS/MS devices. In 11 out of 21 samples (52.4%), no active ingredient was detected, while at least one active ingredient was detected in 10 samples (47.6%).
